Deputy state coroner Christie Clements today handed down her findings after her inquest into the death and found Mr Galeano did not die from being tasered.

Rather, Mr Galeano likely died from excited delirium probably caused by amphetamine toxicity with the tasering a contributing factor.

Senior Constable Myles has been on medical leave since Mr Galeono's death, but Ms Clements found he should face no disciplinary action as a result of his actions.

Ms Clements said while cameras on tasers would not improve the safety of anyone, they would help in establishing a course of events.

Ms Clements also recommended a joint review between the Queensland Police Service and Queensland Ambulance Service be undertaken to ensure officers are trained to work together when responding to "severely disturbed individuals".

On June 12, 2009, after they had received a triple-0 call, Constable Myles and his partner were confronted by Mr Galeano naked in the house of his friend chanting "ABC 123 I'm dead, you're dead, I'm going to kill you".

Constable Myles admitted to deploying the taser eight times, but no more, and Ms Clements accepted he accidentally triggered the taser a number of times.

She recommended Australia introduce similar medical testing for excited delirium to what America has as it is difficult to diagnose.

"QPS should also review the evidence on variation of timekeeping within their organisation, audit the various systems and consider standardisation and monitoring in accordance with a recognised international time keeping standard," her second recommendation said.

Ms Clements said it usually took five people to restrain someone in excited delirium and the chance of death was greatly reduced if the person was in hospital when they were afflicted.

She recommended police be trained to recognise excited delirium and to focus on the urgent medical attention needed by someone in the agitated state.

"A review should be conducted by the QAS and the QPS to ensure that joint protocols and training of officers fully deal with the cooperation required to deal with and great severely disturbed individuals involved in anti-social behaviour showing apparent agitation," the deputy coroner said.

Mr Galeano was released from Townsville Hospital on June 11, 2009, after being admitted suffering amphetamine toxity.

He was in remisision when he was released and Ms Clements found no fault with his hospital care but said it is likely he began taking amphetamines soon after his release.

Mr Galeano's friend, Sandra Wynne, called police to her house in the early hours of June 12 because he was naked and running around the house "smashing it up", according to her police call at the time.

Queensland Police Union president Ian Leavers was at Brisbane Magistrates Court when the findings were handed down.

He said though the police officers had been vindicated Mr Galeano's family had been left "devastated" by his death.

"You can never be happy with a result like this because the fact is one person has been left deceased," he told reporters outside of the court.

Mr Leavers backed the coroners recommendation for a camera on tasers but went one step further and said police should have body video cameras.
